. I To aZZ whom it pray concern.-

Be it known that I, CARL E. KNU'rsEN, of

- the city of New York, borough of Brooklyn,

of New York, have invented certain nea and useful 1m county of Kings, and State provementsinMachines forShapingWrought- Iron, ofwhich the following is a full, clear, and exact specification, reference being had to the accompanying drawings, wherein F 'gure 1 is a side elevation; Fig. 2, a front elevation of my improved anchoriron-shap ing machine; Fig. 3, a sectional view on line 3 3 indicated in Fig. 2 and Fig. :i'is an elevation of a twisting-tool that may be used in connection with my-improved machine, but is not a part thereof.

My invention relates to machines for folding, bending, and otherwise shaping wroughtiron as required .in'the manutactu-re'of various articles and as is ordinarily done by blacksmithing; and my invention consists particularly in devising the hereinafter-dd scribed machine for shaping anchor-irons.

The machine comprises a frame coniposed of uprights 4, ties 5, and braces 6, preferably riveted together, whereon the operative parts of the machine are mounted. The latter comprise an anvil or shaping-block '7, (see Fig. 3,) set up in. socket S, wluch lS'SGCUTed upon the frame by screw-lmlts 9. Block 7 is provided with a semicircular groove 12, and the socket 8 is extended to either sideof the anvil or shaping-block '7 to form flanges 8, snugly inclosing it. Flanges 8 are slotted, their slots 11 being in line with the son1icircular groove 12 of the anvil or shaping-block 7, and the lower termini of slots 11 are semicircular, being of smaller diameter than the groove 12, but concentric therewith. On the outside of the flanges S brackets 14 are set,

and in the upper ends thereof semicircular grooves 14 are provided in line with the slots 11 and corresponding exactly in shape, dimensions, and position with the termini of the slots 11.

A pair of grip-jaws 17 are pivoted on bolt 16, set in flanges 8 'lhesegrip-jaws are two-armed levers fulcrumed on the bolt 16 to move on the outside of flanges 8?. Their shorter arms (designated 18 in the drawings) are hook-shaped and provided with semicircular recesses 19. Their length is calculated to bring these semicircular recesses 19 exactly opposite the semicircular termini of the slots ll'and grip and holdfirm'ly the anchor-pin 32 (see Fig. 3) in its position when the gripjaws are explained. The longer arms of the gri -jaws 17 are suitably curved and pivotall connected by links 21 and bolts 22 and 123 to cross-bar 24. The latter is a double-firmed lever ful rumed on bolt 25, set in braces 6 and having its other terminus shaped into a treadle' 26, by which the grip-jaiws 17 are operated." On the. same bolt 16, but between the flanges 8, the hammer or niovable shaping-block 27 is pivoted.- Thiiblock conforms in shape to theanvil or s 7 and is provided with an armil29, suitably long and terminating'into a handle. It. is also provided with a semicircular groove 28, corresponding in position, shape, and dimension with the groove 12 of the block 7 that is to say, the groove 28 is in such position that when the movable shaping-block 27 is swung around and brought into the position shown in Fig. 3 this groove 28 comes up exactly opposite the groove 12. In this position the taces of blocks 7 and sufliciently to embrace and hold between the two implements a bar of iron folded around a pin, as shown in the drawings.

In the operation of shaping an anchor-iron the'maohine is used follows: A suitablylong piece of flat iron 31 is heated on one end and then placed in the machine in the position shown in Fig. -l, the heated enii resting on the anvil. A11 anchor-pin 32tisf1he laid in slots 11, (see Fig. 1,) its ends re ting in the grooves let of brackets 14. Then the o orator depresses treadle 26,- bringin" there y the grip-jaws in the osition shov in Fig. 3. By maintaining t e pressure 11- the treadle 26 the bar 31 and pin .32 are eld' firmly in position, and theheated end f bar 31 being comparatively soft and the anchorin 32 cold the action of the grip-jatvs on tie pin tends to bend the end of bar 31 and to ress it into the groove 12 of the anvil 7. ext the operator, while still holding treadle 26 in depressed position, swings over the hammer or movable position shown in Fig. 1 to" that shown in Fig. 3. By this motion thd end of anchorbar 31 is coiled around the anchor-pin 32. A downward pressure is then exerted on the 27 are apart Taping-block- ICC shaping-block 27 over from the ends between tlie images-8 end thebreelrets 14. This operation completes the shepingof arm 29 ofxthe shaapinggbloele 27,,wher eby the coil of the bar 3l tll'en lying inthe-grooves 12 and 28 of the blooks'7 and 27 is comr'essedaround the anehofl in 32, that is eld firmly and exently'etvrig t anglesto'the anchor-bar 31 by rip-jaws 18, acting on its the anchor-iromthe pin and bar being thereby firmly and securely joined together. If"
